CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rightsapplication number 2015/1387, filed Jun. 19, 2015, which is hereinincorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Vanda variety ‘SPCDW1507’ is the result of a plannedbreeding program. The new variety originated as a seedling from thecrossing of an unnamed Vanda seed parent (not patented) with an unnamedVanda pollen parent (not patented). Both parents were developed by, andare owned by, the inventor and were never commercially released. Thecrossing was made by the inventor in his research greenhouse inBangphra, Thailand in May of 2003.

The new variety was first selected in February of 2008, in a researchgreenhouse in Bangphra, Thailand belonging to the inventor. Afteridentifying the new variety as a potentially interesting selection, theinventor continued confidential testing and propagation of ‘SPCDW1507’,assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual reproduction of the new cultivar‘SPCDW1507’, by way of mericloning, was first initiated in April of 2008at a commercial laboratory belonging to the inventor in Bangphra,Thailand. Access to all plants was restricted, as plants were kept in agreenhouse not open to the public, and tissue culture plantlets were ina laboratory belonging to the inventor, and not accessible to thepublic. Through six subsequent generations, the unique features of thiscultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1507’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype. The followingtraits have been repeatedly observed and are determined to be the uniquecharacteristics of ‘SPCDW1507’. These characteristics in combinationdistinguish ‘SPCDW1507’ as a new and distinct Vanda cultivar:

-   -   1. Vanda ‘SPCDW1507’ exhibits sepals and petals with a unique        purple-violet color; and    -   2. Vanda ‘SPCDW1507’ exhibits sepals and petals which are        heavily dotted and blotched dark violet; and    -   3. Vanda ‘SPCDW1506’ exhibits sepals and petals with ruffled        margins.

This plant is approximately 6 years old from the time ofmericloning, shown planted in an 8 by 8 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to makethe same in color photographs of this type, the typical foliage of‘SPCDW1507’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to makethe same in color photographs of this type, the typical inflorescenceand flower of ‘SPCDW1507’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in April of 2016describe averages from a sample set of six specimens of six year-old‘SPCDW1507’ plants grown in a greenhouse in Honselersdijk, theNetherlands. Temperatures were approximately 23 degrees Celsius duringthe day and 19 degrees Celsius at night. No photoperiodic or chemicaltreatments were given to the plants. No artificial light was given tothe plants.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘SPCDW1507’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such characteristics are approximations or averagesset forth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climatic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, 2015 (sixth edition).
